Relatively new technology Knauf was developed and offered by the German company Tigi-Knauf, whose main activity is related to the production of high-quality materials for repair and construction work, including plasterboard sheets different types, profiles, fastening elements.
The essence of the technology in the case of ceiling installation comes down to the use of Knauf products with the aim of maximizing the leveling of the ceiling and delicately masking communications with minimal time and labor.
Knauf company focuses on several important nuances, which must be taken into account when assembling a frame for a suspended ceiling using its technology. These include:
With your own hands, a gypsum board ceiling using Knauf technology is assembled from special profiles marked UD and CD.
Properly planned and installed plasterboard structures can not only complement the interior, but also add the necessary accents, adjust the size of the room, and hide communications and electrical wiring. Ceiling installation using Knauf technology allows you to create practical designer ceilings With minimal costs energy and time. Finished design opens up more opportunities for experimenting with light and demonstrates excellent thermal and sound insulation performance.
Installation of ceilings is carried out from the materials included in the kit. It includes sheets of plasterboard from the manufacturer with optimal sizes and properties, metal carcass. Working with such a set is convenient even for a beginner.
It is allowed to install a Knauf plasterboard ceiling only after completion of construction finishing works associated with wet processes. In addition, by this time the walls should be leveled and finished.
Start device process ceiling structure allowed subject to compliance with temperature and humidity conditions. It is important that the temperature is not lower than 10 degrees Celsius and the humidity does not exceed 60%.
The beginning of the work must necessarily be the correct calculation of the ceiling, drawing up a design project, and carrying out markings. At the same stage, the functionality of ventilation, electrical and other communications is checked.
Using a level for control and a tapping thread, mark a line on the walls around the perimeter of the room. Taking into account the type of drywall chosen for installation, mark the guides with points for mounting the hangers.
Suspensions are secured with anchors or dowels in the marked areas. Further work will depend on the choice of a wooden or metal frame.
So, installation technology plasterboard Knauf on the ceiling using a wooden frame suggests the following algorithm:
Some features of installing a metal frame:
The finished frame is sheathed with Knauf plasterboard sheets, again observing some nuances.
When installing a ceiling using Knauf technology, you must adhere to the main rule: the sheets are fixed across the supporting profile with screws at right angles. Before installation, the sheets must be processed in the area of the edge not covered with cardboard to remove the chamfer.
Installation of sheets is carried out with an assistant or using a special lifting mechanism. The sheets are fastened without joints, as already noted, in a checkerboard pattern or staggered. It is correct that the sheet be laid in the longitudinal direction without a gap, while in the transverse direction a small gap would form. Only in this case will it be possible to putty the joint in such a way as to obtain a perfectly even seam.
It must be taken into account that temperature changes will affect plasterboard surface ceiling - the sheets will expand and slightly deform. To avoid serious deformations, special expansion joints are installed in increments of 15 m.
So that the screws do not spoil finishing coating separated by caps, they are twisted with a slight immersion into the sheet to a depth of no more than 1 mm. The joints are sealed with reinforcing tape.
Designing and installing two-level ceilings in accordance with the described technology, it is recommended to increase the strength of the material through the use of finishing based on water-repellent compounds and putty mixtures.
The seams are masked using the following technology:
During installation suspended ceiling The main wishes of the homeowner are to ensure that the structure is strong, durable and attractive, and that the installation work does not take much time. Plasterboard ceilings using Knauf technology meet all these requirements. Let's look at all the features of this technology in this article.
Knauf is a German development. Its developer is the Tigi-Knauf company, which produces high-quality materials for construction and repair - various sheets of drywall, fasteners, profiles, etc.
Knauf is a variant of manufacturing suspended structures using plasterboard sheets, which are attached to a special suspended frame.
When assembling the frame for suspended structure, the company recommends meeting the following requirements:
DIY ceiling frame Knauf technologies mounted using special profiles marked CD and UD.
The advantages of ceilings using Knauf technology include:
The only disadvantage of the technology in question is that when installing such a ceiling, the height of the room is significantly reduced. But this is a minus only in the case of small rooms; for large rooms with high ceilings on the contrary, this can be an advantage.
Work on installing the ceiling in question should be carried out during finishing work. In this case, all wet work must already be completed.
It is important to pre-level all vertical surfaces.
Creation is important for work room temperature and humidity. A room temperature below 10 degrees Celsius is not permissible for work.
Before you begin installing the ceiling, you need to prepare the following tools:
It will not be superfluous laser level, since the frame assembled using the technology in question has a large number of components, the location of which must be strictly level.
The materials you will need are drywall itself and frame elements - a metal profile or a wooden beam.
When making a frame from a metal profile, two types of guides will be needed:
In relation to operating conditions, Knauf plasterboard can be of the following types:
Basically, the frame calculation is carried out taking into account standard sizes plasterboard 1.2 × 2.5 m and thickness 9.5 mm. However, the dimensions of drywall may vary.
The edge of plasterboard is mostly semicircular and thinned, but some sheets have a different edge (straight, with a cut corner, thinned, rounded with a one-sided chamfer or semicircular).
However, the first type of lump is the most technologically advanced. Each of the other non-standard edge types are designed to solve specific structural problems. For example, to mount corner projections.
Frame for stretch ceiling can be made using a Knauf metal profile or using wooden bars.
Suspended ceilings can be of 5 types:
Step-by-step advice from technology developers for those who want to do the work themselves.
More details:
To mark a ceiling mounted using Knauf technology, a conventional building level won't be enough. It is recommended to use a hydraulic level or laser device. You will also need to purchase paint strips.
Having placed marks in the corners of the room using a hydraulic level, they are connected to each other using a cord.
The profile is attached under the intended line, and do not forget that the ceiling will drop by the width of the profile + a sheet of drywall. Therefore, you need to make calculations in advance so that the ceiling is not lowered too much.
On a note: When marking, you should determine the presence of electrical wiring on the walls and ceiling. The places where it is located are also marked so that the electrical wiring is not damaged during the installation of the profile.
After marking is completed, the guides, represented by a 27 by 28 mm profile, are secured. They are fixed to the wall using dowels 6 by 40 mm.
The main requirement for installing gypsum boards using Knauf technology is to fasten the sheets across the supporting profile. The screws must be screwed in at right angles. Previously, the edge of each sheet, not covered with cardboard, is processed to remove the chamfer.
The work is carried out with an assistant or a special one is used for this purpose. lifting mechanism. According to the rules, the sheets are secured in a checkerboard pattern or staggered. In the longitudinal direction, the sheet must be laid without a gap; in the transverse direction, a small gap is formed. This is the only way to achieve a perfect seam after the gap has been filled.
It is important to take into account the possibility of temperature changes affecting the finishing surface, under the influence of which it can expand and deform. If you provide special expansion joints in increments of 15 cm, serious deformation will be excluded.
The self-tapping screws need to be screwed in so that they are immersed into the coating sheet by about 1 mm, so their caps will not be visible on the surface. Reinforcing tape is used to seal joints.
When designing and installing ceilings of the technology under consideration, which have two levels, it is necessary to make the material stronger by using finishing based on moisture-protective compounds and putty mixtures.
Seam masking is done as follows:

Drywall is used to create arches, various decor rooms, partitions, wall openings, etc. Creating beautiful decorative elements cannot do without a strong support, which is represented by Knauf partitions. What is a Knauf partition? In fact she looks like plasterboard construction, in which the frame consists entirely of a metal profile. The design is created using a special technology that eliminates various unforeseen circumstances.
Knauf partitions can be different. They are installed in different rooms, with different sound insulation, for different purposes. Partitions can be different types and are divided according to certain parameters.
According to their design, partitions are divided into:
In addition to these types, there are partitions with built-in special channels for ventilation and communication. Next parameter, according to which the partitions are divided - this is the frame, or rather its type. Frames can be double or single.
The use of partitions based on a double frame is recommended if you need to create a strong a reliable wall, which will withstand heavy .
Creating partitions with single frames is recommended in places where sound insulation is not so important and the walls will not be burdened with heavy pieces of furniture or appliances. We can conclude that the double frame is more durable.
Why is drywall so popular? Knauf partitions? Since the 90s, drywall has been almost synonymous with the word European-quality renovation. On Russian market this material appeared thanks to the Knauf company. The material was accompanied by instructions that described in detail how to create various designs from plasterboard sheets. The technology has gained great popularity due to the excellent quality of the product.
The main advantages of Knauf plasterboard partitions are as follows:
The use of Knauf partitions is still popular today. The correct selection of a set of partitions can provide excellent sound insulation, high strength and reliability of the walls. As mentioned above, there are different strengths and sound insulation, depending on the type of room you should choose a suitable kit.
The installation technology using the Knauf system is not much different from the standard installation procedure. However, there are still some differences, which will be discussed below. Together with the drywall material, the Knauf company brought special technology And general recommendations for the installation of partitions.
They look like this:
In addition to the above recommendations, it is necessary to take into account the installation features of the frame. In order for the entire system to serve for a long time, you need to ensure that the joints from the gypsum plasterboard partition above the door opening are not located on the racks attached to the frame. Instructions for assembling the frame for fastening gypsum boards in our material:.
In addition, the seam must be made so that it is in that part of the intermediate guide that is located above the horizontal beam. Horizontal beam serves as the upper limit. Following these recommendations will help you make a long-lasting, high-quality design.
Exist Various types partitions that suit different room parameters. At the moment, there are about 25 kits for installing partitions using the Knauf system on sale. All sets are marked with the letter "C", which is combined with a specific set number.
To select the right installation kit, consider the following factors:
Having decided on the parameters of the room, it will be much easier for you to choose a partition. For example, a bedroom adjacent to the kitchen or living room requires a high degree of sound insulation, so the installation kit should be selected accordingly. If the bedroom is adjacent to the wall of the neighboring apartment, then even more so the partition should have a high degree of protection from unwanted noise.
Plasterboard partitions Knauf - worthy and reliable way to build a wall in the desired location. Simplicity and ease of use and installation will help make the installation process easy and enjoyable. With this technology, the issue of unnecessary noise will be closed for you forever.
Many craftsmen who install suspended ceilings have mastered the technique in practice, adopting the necessary experience and knowledge from more experienced installers. But when the work requires drawing up a work project, and at the end it is necessary to provide reasonable guarantees of the technical compliance of the design with SNiP standards, many experience difficulties. Craftsmen from any reputable organization design and install plasterboard on the ceiling in accordance with the recommendations contained in the standard routing Knauf.
If for an amateur GOST and SNiP are a “dark forest”, then for a professional the technological map is a universal guide on how to technically and quickly assemble a frame and screw drywall.
Important! If the work is performed under a contract, then when placing and submitting an order you cannot do without the recommendations of the Knauf technical map for drawing up project documentation.
The latest current Knauf technological map (series 1.045.9-2.08.1) is comprehensive on how to design and install a suspended ceiling structure under plasterboard and gypsum fiber boards. All work is divided into separate sequential stages, so understanding the technology will not be difficult.
The frame for the ceiling is made of metal Knauf profile, and from wooden blocks.
There are 5 types of suspended ceiling designs:
For wooden structure P 111 uses coniferous bars with a moisture content of no more than 12%. Before installation on the ceiling, they are treated with an antiseptic and fire retardant. The recommended cross-section of the bars is 50×30 mm.
The metal frame for the ceiling is made of long rolled elements made of thin sheet steel.
Frame with fastening to the base (P 112, 113). To assemble it, take a regular ceiling profile. It consists of the following elements:
The ceiling of the P131 system with fastening to the wall is made of a more powerful profile for the installation of partition structures (PS).
To strengthen the structure at the junction of rooms, use reinforced profile UA on the ceiling.
Profile connection work is performed using the following elements:
Frame installation work Knauf ceiling performed using the following elements:
Important! Not everyone knows that U-shaped hangers are produced under the profile and under the beam. Although they are similar in appearance, they have different nominal sizes after folding the side strips. For wood it is 50 mm, and for a profile – 60 mm.
Depending on operating conditions, required drywall Knauf is chosen from the following varieties:
Type A. Regular construction drywall. This sheet is used for heated rooms with normal level humidity (up to 60%).
Type H2. Drywall with increased moisture resistance. The leaf has a low level of water absorption (up to 10%). Room humidity can be up to 75%.
Type DF. Flame resistant drywall.
Type DFH2. Drywall with the properties of the two previous types.
Important! Initially, it is customary to calculate the frame specifically for ceiling plasterboard size 1.2x2.5 m and thickness 9.5 mm. But drywall comes in other sizes.
The drywall has a factory-made longitudinal edge. The most technologically advanced and therefore widespread is the semicircular thinned one, but there is plasterboard with other types of edges:
Each type of edge is needed to solve specific structural problems. In particular, installation of figured corner protrusions.
The work is carried out in a dry and heated room at an air temperature of at least +10 degrees.
Work on the implementation of any frame begins with marking the design position of the ceiling surface. Using a level and a tapping thread, mark the corresponding line on the walls around the perimeter.
Further, depending on which Knauf drywall is selected for suspended ceiling, work is being done to mark the location of the guides and mounting points for the suspensions. The lines of the supporting guides are marked in accordance with the length of the sheet so that the end joint falls on the profile.
At the marked points, hangers are attached to the ceiling with dowels or anchors.
The wooden frame is mounted in two ways:
Installation of a profile frame:
Important! The edge of the sheet, not covered with cardboard, is processed with a plane to remove the chamfer.
The manufacturer has prepared a video in which craftsmen demonstrate the principle of assembling a suspended structure
The work of screwing Knauf sheets is performed in pairs or using a lifting mechanism. Plasterboard is mounted on the ceiling without T-shaped joints, staggered. In this case, the sheet is shifted by the step of the supporting profile. Installation is carried out so that in the longitudinal direction the sheet lies without a gap, and in the transverse direction there is a small gap. This way the putty will completely fill the joint, and the seam will be strong.
When temperature changes, the plasterboard sheet expands, so large rooms it is necessary to provide expansion joints with a pitch of 15 m.
To make it easier to putty the self-tapping screws, screw them in with the head slightly recessed into the sheet – 1 mm. The work of sealing joints is carried out using reinforcing tape.
Drywall – universal material, and the Knauf technological map will help you complete high-quality installation any design, even for a novice master.
One of the most technologically advanced and economical solutions for construction or apartment renovation is the installation of gypsum board sheets. With their help, you can easily correct all wall defects, achieving perfect flat surface. The effectiveness of gypsum boards in the manufacture of decorative elements, arches or boxes has been proven by numerous design implementations. Among the total number of manufacturers plasterboard material the German company stands out favorably Knauf, whose products meet all international standards. The components used in production do not contain any toxic elements and do not cause harmful influence for human health.
Plasterboard sheet is a three-layer structure consisting of two outer layers made of cardboard and internal from gypsum mixture . Depending on its composition Knauf plasterboard and its price are divided into:
The types of sheets can be easily determined by external signs: moisture resistant varieties have green color cardboard, A ordinary – grey.
The technological composition of the first type differs from others in the presence of antifungal and hydrophobic additives, as well as special cardboard.
By purpose GCRs are divided into three types:
In addition, sheets may have various types of longitudinal edge, which Knauf technology for installing drywall used for subsequent puttying of joints.
Material Dimensions rectangular shape are from 2,000 to 4,000 mm in length, and 600 or 1,200 mm in width.
The preparatory stage includes assessing the working surface for installation and choice the necessary tool . The company’s specialists advise preparing:
The surface is inspected in order to determine the material of the walls and their operating conditions. After this, a specific choice of gypsum boards and consumables is made.
Depending on the type of structure, as well as its purpose, plasterboard sheets can be attached both on glue and on metal or wooden frame . It must be said right away that wood is not the most the best choice, especially in areas with high humidity.
The use of glue for fastening is permissible for wall unevenness that does not exceed 4 mm. In other cases, it is recommended to use a galvanized profile.
For the middle room you need to prepare about 30 kg dry glue mixture Knauf Perlfix . It will provide reliable fastening without unnecessary structures, medium price of mixture for plasterboard Knauf – 285 rub. per package 30 kg. Fastening method sheets is as follows:
Important! The mixture begins to harden after 10 minutes. During this period of time, the slabs should be leveled using a rubber hammer and a beam.
This plasterboard installation technology from the Knauf company allows for high-quality insulation and sound insulation of walls. After taking measurements, the process continues the points:
Important! To improve sound insulation performance, it is recommended to attach a special self-adhesive tape to the UD profile. The heads of the screws must be recessed into the mass of the slab; here it is advisable to use a special bit for a screwdriver with a limiter.
The cost of gypsum plasterboard is primarily influenced by its type and parameters. For example, average prices for different kinds material:
When purchasing, you should think in advance and calculate the total amount of material, profile elements and fasteners. This will make it possible to organize a wholesale purchase that will make price of Knauf plasterboard sheets somewhat lower.
